Application filed January 13, 1913. Serial No. 741,673.

the leather to the operation of an ironing machine, the foregoingoperations or finish ing steps requiring a wnsidcrablc expenditure oftime and necessitating the employment of a plurality of machines andusually two sets of operators to attain results which are inferior tothose which lobtain in my present novel construction of leathermacllllle.

By my present invention I have provided novel means for glazing andironing a piece of leather at one and the same operation and in one and.the same machine, whereby I at tain results far superior to any of theresults heretofore attained, wherein a plurality of the machinesheretofore referred to are employed, the leather finished in my presentnovel construction of machine possessing a smoother grain and in manyinstances a finer tinish than it has heretofore been possible to obtain.by any means heretofore known or employed in this art.

My invention is intended to be used primarily on glazed kid and on calfskins of various grades, altlunigh it will of course be understood bythose skilled in this art that the machine is capable of a wide varietyof other uses, and l do not therefore desire to be limited to anyparticular grade of leather or class of work to which the same may beapplied.

lVith the above in view, my invention in its broad and generic scopeconsists of novel means for controlling the operation of glazing devicesand independent finishing devices with respect to the skin beingtreated.

My invention further consists of a novel construction of head orparallel. bars carryingthe operating tools and adapted to be raised andlowered at suitable points during its longitudinal travel, so that thenonrevoluble glass and the rotatable roll will contact with the leatherto he treated at the same instant of time and will raise out of contactwith the leather at the same instant.

It further consists of a novel construction of a movable head carryingin its forward portion a rotatable roll of any suitable matcrial havingpreferably a smooth surface, said head also carrying a non-revolublcglass coacting therewith, novel means being provided for affecting thesimultaneous recipmention of the roll and the glass and for alsoaffecting the elevation and forward movement of said roll and glass,whereby the two latter descend upon and contact with the leather to betreated at the same instant.

My invention further consists in a novel construction and arrangement ofa plurality of links or pendulums whereby I am enabled to attain auniform and simultaneous actuation of the leather treating devices, andnovel means for intermittently raising and lowering such links orpendulums.

It further consists of a novel construction of a smooth roll for glazingor ironing pur poses.

In prior devices employed for ironing purposes it has been necessary toartificially heat the same while in my present mechanism the necessaryheat is developed front the friction of the roll on the skins beingironed.

It further consists of novel means for causing the glazing means and theironing means to travel in a straight line during the working stroke andto return the same in a curved line to thepoint where the working strokebegins.

I t further consists of other novel features of construction, all aswill be hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in theaccompanying drawings a preferred embodiment which is at presentpreferred by me, since the same has been found 111 practice to givesatisfactory and reliable results, although it 18 to be understood thatthe venous instrumentalitics of which my invention conslsts can bevariously arranged and organized and that myinvention is not limited tothe precise arrangement and organization of these instrumentalities asherein shown and described.

Fig. is a side elevation of asupporting device for an agate or glass burnisher. Fig. 6 is aperspective view of a guide, and a block adapted to slide thereon. Fig.7 is a front elevation of a portion of a roll employed and means forsupporting the same. Fig. 8 is a front elevation of the parts seen inFig. 5. Fig. 9 is a side elevation of certain of the parts seen in Fig.7.

Similar numerals of reference indicate corresponding parts in thefigures.

Referringto the drawings:-The frame of the machine comprises sidemembers 1 and 2 which are retained in proper position with respect toeach other by braces 3, 1, 5 and 6. Journaled in the side member 2 is adriving shaft 7 provided with a tight and a loose pulley 8 and9-respectively. The inner end of the shaft 7 has rigidly secured thereonan arm 10 in which is fitted one end of a rod 11 firmly secured in saidarm by a set screw 12 or equivalent fastening devices, so

, that this shaft is prevented from rotating in said arm. The oppositeend of the rod 11 is fitted into an arm 13 and is firmly secured theretoby a set screw 1 1 to prevent rotation of said rod 11 in the arm 13. Theobject in securing the rod 11 in the arms 10 and 13 is to cause a pulley.15 fast on said rod 11 to be carried around by said arms 10 and 13, asan integral part thereof, so as to impart a rotary motion to a pulley 16without varying the distance between it and the pulley 15 when the bars17 and 18, in which said pulley 16 is journaled, are reciprocating. Thearm 13 is rigidly secured to a shaft 19, journaled in the member 1 ofthe frame of the machine, and this shaft 19 has fast thereon a cam 20,adapted to operate a lever 21 fulcrumed at 22, in the side member 1 ofthe frame.

23 and 2a designate links one end of each of which is loosely mounted onthe rod 11 while the opposite ends of said links are loosely fitted on,a shaft 25 carried by the bars 17 and 18 so that when the arms 10 and 13are in operation they impart a reciprocating motion to said bars andtheir adjuncts. The bars 17 and 18 have pivoted thereto, at 26 and 27,the lower ends of the levers 28 and 29 respectively. The upper extremityof the lever 28 is pivoted at 30 to a link 31, theend of which oppositeits pivotal point '30 is loosely fitted on a stud shaft 32 that projectsfrom a standard 33 carried by the machine frame. The end of the link 29opposite the pivotal point 27 has secured in it a shaft 34% adapted toslide up and down in guides that depend from the cross piece 36 thatconnects the upper portions of the standards 33 and 37. The standard 37is carried by the side member 1 and standard 33 in side member 2 of theframe. The lever 28 has pivoted thereto, as at 38, one end of a link 39whose opposite end is pivoted to a stud. or pintle 10, rigidly fixed inthe frame of the machine. The lever 29 has pivoted thereto as at 41, oneend of a link 42 whose opposite end is pivoted at 43 to a block 14 sothat the rising and falling motions of said block 4 1 may be transmittedto the link 42, and its adjuncts. Projecting from the standard 37 is astud shaft 45, on which is pivoted one end of a link 16 whose oppd siteend is pivoted to the shaft 3 and is adapted to move in unison with thelink 31 in order to properly actuate the lever 28. The lever 29 haspivoted thereto, as at 17, in Fig. 2, one end of a link 18 whoseopposite end is pivoted at 19 to a block 50 so as to move up and down inunison with said block 50 and operate the lever 29 and certain of itsadjuncts. The block at has pivoted thereto as at 51, in Fig. 1, one endof a sleeve 52 that is screw threaded to receive one end of a rod 52whose opposite end is also screw threaded to engage a sleeve pivoted atto an arm 55, the latter being secured to a shaft 56 ournaled in theframe of the machine.

The shaft 56 has secured thereto an arm 57 to which is pivoted as at 58,sleeve 59 that is screw threaded to receive one end of a rod 60 whoseopposite end is also screw threaded to engage a sleeve 61 pivoted at 62,see Fig. 6, to the blocks 50, so that when said rods and 60 move up anddown by reason of the rocking of the arms 55 and 57, such up and downmotions are transmitted to the blocks 44L and 50 and their adjuncts. Theshaft 56 has secured thereon an arm 62, see more particularly Fig. 1, towhich is pivoted a sleeve 63 screw threaded to receive one end of a rod6-1 whose opposite end is screw threaded to engage a sleeve 65 that ispivoted at 66 to the lever 21. The screw threads on the rods 52, 60 and64 are preferably right and left hand threads for the purpose ofadjustment of said rods and their adjuncts. Pivoted in the upper portionof the lever 21 is a. roller 67 that is located in the cam groove in thearm 20 so as to impart a rocking motion to said lever 21.

As will be seen in Figs. 1 and 3, a belt 69 passes partly around thepulley and partly around the pulley 16 so that a rotary motion may beimparted to the latter from the pulley 15.

The shaft- 25 has fast thereon a pulley 70 partly around which passes abelt 71 that also passes partly around a pulley 72 fast on a shaft 73carried by the bars 17 and 18. The shaft 73 has fast thereon a gearwheel 741T that meshes with a gear wheel 7 fast on, a shaft 76 journaledin the bars 17 and 13. The shaft 76 has fast thereon a pulley 77 partlyaround which passes a belt 78, said belt passing also partly around apulley 7 5) fast on a shaft 80 journaled iu plates 81 guided in the bars17 and 18, as best seen in .lfiip'. 7 so that a finishing or ironingroll 82, fast on the shaft 80 may more up and down with the plates 81accorsiling to the varyin thickl'iess of a skin unde L ling the process01 glazing. The plates are each :tormedwith a slot as seen in l igs. 1 7and 9, and through each of which passes a bolt 8-1 to properly guidesaid plates in their up and down movements. The plates 81 are providedwith cars 85 adapted to receive the lower extremities of screwtl'u'eaded rods 80, providetl with nuts 87 and 88 so as to properly-idjust the position of the roll. 82 with respect to a skin to beglazed, and furthermm'e to adjust the pressaire of said ironing orfinishing roll 82 upon said skin, it being noted that a spring 89encircles each rod 80 and is interposeil between the nuts 88 and a bracebar 00.

The bars 17 and 18 have secured thereto a brace bar 91 through whichpasses the screw threaded rods 92 provided with nuts 93 and 04, see moreparticularly ,Fig. 8, so that the position of the glazing member 1):),of agate, glass or other suitable material, as well as the pressure ofsuch glazing member upon a skin may be adjusted as desired. spring 00encircles each rod 92 and placed between the nuts 9 1 and the brace bar01. The lower extremity of each rod is pivoted at 97 to a jaw 98 whichwith a jaw 99 is adapted to firmly clamp the glazing member between themso as to cause said member 95 to follow the movements oi the bars 17 and18.

interposed between the member 05 and the clamping jaws 9S and 99 is acushion 100 ol soft material to prevent injury to the glazing; memberThe jaw 09 is provided with adjusting nuts 1,01 and 102 adapted toregulate the 'iressure of said jaws 0S and 09 against the glazing member05. The bars 17 and 18 are each provided with studs 103 that act as aguide for the stem 10 1 of the jaw in order to prevent longitudinalmovement ot said stem. The jaw 08 has pivoted thereto, as at 103, oneend of tension bars 106 whose opposite ends are connected at 1.07 to thebars 17 and 1S. Said bars prevent lateral movement of said jaw, while itis free to rise against the springs 96.

It will be seen on referring to Figs. -3 and 8 that the jaw 98 providedwith two tension bars 106.

it will be best seen from Figs. 1 and 3, that a table or worl: support108 is fitted in a framework 109 and is provided with inclined 'l'aces110 and 111 that rest upon similar inclined aces 112 and 113 on asliding member 11 1- guided in the framework 109. The sliding member 111is in screw threaded engagement with a rod 115 swiveled in saidFrame-work 1.09 and provided with a handle [.16 whereby said rod 115 maybe rotated so as to cause the member llteto move to and. tro andconsequently raise, or lower the table 108. The table 108 is providedwith a strip of metal or other desired material 117, upon which isplaced a cover of leather or its equivalent 118 upon which a skin to beglazed is placed. In the present instance the outer extremity 119 oi thelayer or cover 118 is secured to the table 108, while its opposite endis provided with hooks 120 in screw threaded engagement with the. nuts121 whereby said cover 118 may be tightened under a desired tension uponthe table 108.

The operation of my novel leather finishing machine is as follows:,Be'lt'ore lleginning the detailed description oil the operation,attention is directed to the fact that in my present invention, l employglazing; means and ironing or finishing u sans located posteriorthereto, in conjunction with mechanism tor causing such means to act onthe leather during its travel in one direction, and for simultaneouslyelevating said means or bringing them out of contact with the leather sothat on the return travel they will not engage with the leather whichbeing treated. The pulley 8, driven by any desired source :1, power,transmits motion to the shaft 7 and through the arm 10, rod 11 arm 15-1,and shaft 19 imparts motion to the ram 520 last on the shaft 10. Theturning of the arms 10 and 1?) about 7 and 10 as an axis imparts artwiprocating motion to the bars 17 and 18, through the links 23 ard 2i,it being apparent that the pulleys, gear wheels, ete, :arricd by saidbars move in unison therewith. hen the lHIl'S 17 and 18 are in theposition seen in Fig. l. the ejlass or agate S2 and roll 05 are in theirextreme right hand position and press upon a skin to he glazed upon thetable 108. The arms 10 and '18 in turning from the position seen in Fig.1 into that seen in Fig. El bring the bars 17 and 18., and consequentlythe glazing means and finishingroll 05 into their extreme left handposition. it.beiug understood that during the t and of the glazing means852 and roll 05 in the direction just stated. the two latter bearagainst a skin placed upon the table 108 so as to glaze and iron saidskin. It is apparent that since the pulley 1:1 is fast upon the rod 11it will impart a rotary motion to the pill ley 1th through the belt 09.when the arms 10 and 13 and pulley '15 are turning in the. direction in(licated by the arrow 7) in Fig. 1 and around the shalt 7 as an axis. Therotary motion of the pulley 10 is transmitted to the pulley 70. throughthe shaft 25; and coiwequeiitly imparts motion to the pulley 7:2, sha'tt73, and gear wheel 74: through the belt 71. The gear wheel 74 transmitsmotion to the gear wheel 75 causing the shaft T0 and pulley 77 fasttl'iereon. to turn in a direction opposite to that of the arms 10 and18, or in the direction indicated by the arrow c in the right handextremity of Fig. 1, it being observed that motion is imparted to thepulley T 9 from the pulley 77 through the belt Referring now to Fig 1.it will be observed that the lever 21 remains stationary during thetravel of the glass 8'2 and roll 95 from right to left by reason of theroller 6?, carried by said lever 21, occupying a position within thedwell portion 4 in the cam groove (58. l l hen the glass 82 and roll 95have completed their movement from right to left, and in contact with askin to be glazed, the bars 17 and 18 and the part carried thereby startto move from left to right and simultai'ieously with this movement, thedwell portion 6 in the cam groove ('38 is brought in contact with theroller 07 as will be understood from Fig. 4t, whereupon the lever 21 isturned upon its fulcrum 22 and is brought into the position seen indotted lines in F 1, whereupon a partial rotation is imparted to theshaft 50 cans ing the arms (32 and 55 to move into the positions seen 11dotted lines. This change in the position of the arm 55, and likewise ofthe arm 57 seen in Fig. 2, or uses a downward movement of the rods 52and (30 thereby lowering the blocks 4% and 50' to which they areconnected. lVhen the blocks 41- and 50 are in their lowermost positionsthe shaft 34L is moved from its position seen in full lines in. Fig. 1into that seen in dotted lines in said figure. This downward movement ofthe shaft 8% brings the levers 28 and 29 into the positions seen indotted lines, whereupon the inner ends of the bars 17 and 18 are loweredwhile their outer ends are elevated, thereby removing the glass 95 androll 82 from contact with a skin undergoing treatment. The glass androll 82 remain in their elevated positions during the travel of the bars17 and 18 from left to right, Fig. 1, due to the dwell e in the camgroove (38. 1 hen the bars 17 and 18 have completed their movement inthe di rection just stated, the dwell (Z in the cam groove 68 is againbrought in contact with the roller 67 thereby rocking the lever 21 andcausing the rod 64- to move the shaft and thus elevate the rods 52 andG0 and consequently the shaft 34 through the mechanism hereinbeforedescribed. Vhen the shaft 84 is in its elevated position it returns thelevers 28 and to the positions seen in full lines whereupon the and roll82 are again brought into contact with a skin to be glazed and theoperation herein described is repeated until the process of glazing askin is completed.

Attention is directed to the fact that the links have a fixed fulcrum at10 which causes the center of the pendulums 28 to travel in arectilinear path in their movement in both directions. The links 42 havea movable fulcrum, the movement of which causes the pendulums 29 toguide the bars 17 and 18 and cause the glass 95, and the roll 82 totravel in a straight line during the working stroke and return the samein a curved line to the point where the working stroke begins.

The operator moves the skin being glazed over the table 108, in theusual manner, so as to present all parts thereof to the members 82 and95. As hereinbefore stated, the glazing glass 95 is firmly clampedbetween the aws 98 and 99 to prevent the same from rotating under normalconditions. The glass 95 and roll 82 are yieldingly supported so thatduring the process of glazing and finishing, they are permitted toindependently move up and down to compensate for varying thickness of askin owing to the provision of the springs 89 and 96. The space betweenthe glass 95 and roll 82 relatively to the table 108 and likewise thepressure of these upon a skin to be treated, may be ad justed by turningthe nuts 87, 88, 93, and 9 1 on their respective rods 86 and 92 eitherto the right or to the left according to requirements. The space betweenthe glass 95 and roll 82, relatively to the table 108, may also beadjusted by turning the crank handle 116 so as to rotate the screwthreaded rod 115 either to the right or to the left in order to causethe sliding member 114. to move inwardly or outwardly and by reason ofthe inclined faces 110, 111, 112, and 113 raise or lower the table 108.

Attention is directed to the fact that both the glazing member 95 andthe ironing member 82 are simultaneously brought into contact with theleather to be treated at the beginning of the operative stroke, and aresimultaneously moved out of engagement with the leather when suchoperative stroke is completed.

Attention is also directed to the fact that the ironing or finishingroll is yieldingly mounted at a point posterior to the glazing member95, and also that the glazing mem ber 95 is yieldingly mounted so thateither the glazing member or the ironing roll is permitted to have anindependent vertical travel in accordance with the variation inthickness of the leather which is being treated.

It will also be seen that relative adjust ment of the leather treatingdevices and the work support is provided either by adjusting the leathertreating devices themselves or by manually adjusting the height of theleather support.

. Attention is also directed to the novel manner of imparting areciprocating movement to the glazing and finishing means, and the novelmeans provided for causing the revolution of the ironing or finishingmeans during its reciprocation.

In so far as I am aware, I am the first in theart to devise a leatherfinishing machine, wherein a continuously revolving ironing member ismounted posterior to the glazing member, and means for causing the sameto sinmltaneously contact with the leather during their travel inonedirection, so that the ironing means treat the surfaceof the leatherwhich has just been acted on by the glazing devices, and it isunderstood that my claims to such features are to be construed withcorresponding scope.

It will be further apparent that the entire operation of the machineisautomatic, so that the only attention required by the op erator is toshift the leather being treated, so that the entire surface will beacted upon in the manner herein described.

The smooth roll may be located in practice, either anterior or posteriorto the glazing means, but for purposes of illustration I have preferredto show the same as being mounted posterior to the glazing means, sincesuch arrangement has been found in practice to give very marked andadvantageous results, although it will of course be understood that I donot desire to be limited to the arrangement shown for the purpose ofillustrating one manner of 'arrying out my invention in practice.

It will now be apparent that I have de vised a novel and usefulconstruction of a leather treating machine, which embodies the featuresof advantage enumerated as desirable in the statement of the inventionand the above description, and while I have in the present instance,shown and described a preferred embodiment thereof which has been foundin practice to give satisfactory and reliable results, it is to beunderstood that the same is susceptible of modification in variousparticulars without departing from the spirit or scope of the inventionor sacrificing any of its advantages.
